After research, I realize now that by shocking the pool (an above-ground SummerEscapes 18x48 with the standard 1500gph filter) isn't quite going to kill the algae that has suddenly emerged in our pool's shady side. I have a phosphate remover, an algaeside and a flocculant on order. However, I'm concerned how to vacuum it all up once it's dead. I have a Skooba Pool Vacuum that *usually* does a fine job, but with the algae, it just seems to "slime" the debris bag, making it useless. Any ideas??
